Phase I: Assembly Validation

  • HEPI
  • Overview: Mechanical assembly (no Instruments)
  • No particular tests (rigid connection between cross beams and piers). No report.
  • Final check is the leveling.
  • Assembly validation is responsibility of SEI installation lead (Jeremy @ LLO, Hugh @LHO)
  • HAM-ISI
  • Overview: Sub-assembly check, Inventory, Balancing, Check & adjust gaps, Range of motion, Static tests, Linearity tests, Power spectrums, Transfer functions…
  • Main page: E1000305 - aLIGO HAM-ISI Testing and Commissioning Documentation
  • Procedure: E1000309 - aLIGO HAM-ISI, Pre-integration Testing Procedure, Phase I (post-assembly)
  • Report Example: E1000326- aLIGO HAM-ISI, Pre-integration Test Report, Phase I, LLO Unit #2
  • BSC-ISI
  • Overview: Similar to HAM-ISI. Twice many stages.
  • Main page: E1000306 - aLIGO BSC-ISI Testing and Commissioning Documentation
  • Procedure: E1000486 - aLIGO BSC-ISI Testing Procedure, Phase I (Post-assembly)
  • Report Example: E1100294 - aLIGO BSC-ISI, Pre-integration Test Report, Phase I, LHO Unit #1

Phase II: Integration

  • Everything between the end of the module assembly and closing the chamber.
  • In other words, all the testing related to merging with other modules
  • HEPI
  • Overview: Check that HEPI is ready to receive an ISI or Stack (Stops, Leveling…)
  • Check actuators and sensors (L4C power spectrums, IPS DC values…)
  • Install ISI (or passive stack)
  • Unlock HEPI. Monitor dial indicators, load cells.
  • Level HEPI.
  • Connect actuators.
  • Set IPS gaps.
  • Check the control software (SEI and SUS Watch dogs)
  • Test HEPI (Range of motions, Transfer functions, turn on low performance loops)
  • Leveling, alignments.
  • Report and validation of phase II.

Phase II: Integration

  • Everything between end of the module assembly and closing the chamber
  • In other words, all tests related to merging with other modules
  • HAM-ISI
  • Phase II starts when the HAM-ISI unit is mounted on a stand in the observatory (LVEA or End Station)
  • Two-case scenario:
  • Assembly already completed and fully tested in the assembly building (i.e. HAM-ISI 8 & 9 @ LHO)
  • Minimum side chamber testing before insertion (DC values of CPS, power spectrums of GS13s…) . Could be done without electronic rack if not available. Testing completed after the chamber is closed.
  • Assembly completed in LVEA or End Station (Install GS13, CPS Shield…)
  • Need Side Chamber Testing before Installation.
  • After installation in the chamber:
  • - Platform is being populated with optics
  • - Testing sequence to be detailed chamber per chamber.
  • Report, Validation
  • Close the chamber: End of Phase II
  • Phase III: Control Commissioning
slide7

Phase II: Integration

  • Everything between end of the module assembly and closing the chamber
  • In other words, all tests related to merging with other modules
  • BSC-ISI
  • Phase II starts when the BSC-ISI unit is mounted on stand in the observatory (LVEA or End Station)
  • Check functionalities (Static Tests, Transfer functions). Compare with measurements after assembly (Phase I)
  • Test control functionalities (Damping, Level 1 control…)
  • Integration with optical components. Testing is chamber specific, function of the optics installation sequence.
  • Installation in the chambers
  • Test basic control functionalities in the chamber (Damping, Level 1 control…)
  • Report, Validation
  • Close the chamber: End of Phase II
  • Phase III: Control Commissioning

Phase III: Control Commissioning

  • Everything after closing the chamber and before hand-off to operations
  • HEPI: Control strategy developed for iLIGO
  • Detailed step by step procedure based on the BSC-ISI model
  • Being tested at LASTI
  • Procedure being written

Performance Levels

  • HEPI
  • Basic control functionality tests during HEPI checkout (Phase II)
  • Regular performance control loops, Sensor Correction (Phase III)
  • HAM-ISI and BSC-ISI
  • Low Frequency control:
  • High Blend: Low performance ~ 1 Hz Blend frequency Phase II
  • Medium Blend: Medium Performance ~ .3 Hz Phase III
  • Low Blend: High Performance ~.1 Hz Phase III
  • High Frequency Control:
  • Control Level 1 : Low performance ~ 10 Hz Unity gain frequency Phase II
  • Control Level 2 : Medium Performance ~ 20 Hz Unity gain frequency Phase III
